Design a Custom BoardAbout This Component
8-bit AVR microcontroller with 4KB in-system programmable flash memory, 256B EEPROM, and 256B SRAM. Features 6 I/O lines, 10-bit ADC with 4 single-ended and 2 differential channels, dual 8-bit timers with PWM outputs, USI serial interface, and internal oscillator. Operates at 2.7-5.5V up to 20MHz with ultra-low power modes consuming 0.1µA in power-down.
Package: SOICW-8 (5.3mm wide) · 8 pins
Why does this need a breakout?
This SOIC-8 package is too small to hand-solder reliably and incompatible with breadboards. A breakout board brings 1.27mm pitch pins to standard 0.1-inch spacing, enabling prototyping without specialized equipment. Ideal for memory and sensor ICs that demand convenient development while preserving the compact footprint.
